Improvement in condensers



UNITED STATES PATENT OEEICE.

GEORGE STUMP, OF NEW YORK, N. Y.

IMPROVEMENT IN CONDENSERS.

To all 'whom it may concern:

Be it known that I, GEORGE STUMP, of the city, county, and State of New York, have invented a new and Improved Condenser and Heater; and I do hereby declare that the following is at'ull, clear, and exact description of the saine, reference being had to the accompanying drawings, forming a part of this specification, in which- Figure l represents a longitudinal vertical section of my invention, taken in the plane indicated by the line w, Fig. 2. Fig. 2 is a pl in or top view of the same.

Similar letters of reference in both views indicate corresponding parts.

To enable those skilled in the art to make and use my invention, I will proceed to describe it with reference to the drawings.

Arepresents the receiving-chamber of a condenser or heater, and B its dischargingchamber, steam being admitted through the pipe a, and the condensed water or spent steam being carried oft' through the pipe b. Thechambers A and B are secured between two sheets, C, by means of screws c or by any other suitable means, each chamber being cast separate. 4

D lD represents several ranges of tubes,

`which are bent in the form of the letter C.

Their ends are secured in the tube-sheets (l in such a manner that each of said Cshaped tubes communicates with both chambers A B, as clearly shown in Fig. l of the drawings. These tubes ought to be placed as close together as the strength ot' the tube-sheets will admit, and they are curved so that the condensed water accumulating in the same will readily lind its way to the lower or discharging chamber, B.

The chambers A B, with the tubes D, are introduced into a tank, E, to which water or other suitableliquid is admitted through pipes d, and which isl provided with an overflowpipe, e, so that the condenser or heater is or may be completely submerged under water, or other liquid, if desired.

The steam which passes from the chamber A through the tubes D D condenses in said tubes, and the condensed water readily flows oft' to the chamber B, from which it is discharged through the pipe b. By reason of their peculiar shape the tubes D D offer a large condensing or heating surface, and they can be inserted perfectly rigid into the tubesheets (l.

When it is desired to clean the tubes, the tube-sheets are removed and free access can now be had to all the tubes.

If it should be desirable to repair one of the tubes or tubesheets, it can easily be removed and replaced, if desired, by another, without disturbing the chambers -A B or any other part of the condenser.

In my condenser the tubes D, it will be noticed, are of curved form, which permits them to expand or contract without ait'ecting the joints. Each tube, when it expands, curves out a little more than before, and when it contracts -its curvature is reduced without eii'ect ing its own joints, and, furthermore, each tube can expand and contract independent otl any of the others. The inner tubes, for instance, ma y be liable to greater changes than the outer tubes, and in ordinary tubular condensers the joints become leaky from this very reason, because the inner tubes expand and contract more than those near the edges ofthe tube-sheets,and consequentlythe joints must work loose.

B v my condenser or heater a very large condensing or heating surface is produced, and when once properly fixed the `joints are not liable to work leose. It is particularly adapted for marine-engines, where it is peculiarly objectionable it' the condensingliquid is mixed with the condensed water; but it may be used with equal advantage on engines of every description, or i'or heating water or any other kind of liquid.

By having the chambers A B made separate and independent, they can be removed separately for repair or renewal at pleasure, and at--the same time they strengthen and preserve the tu'besheets C from injury.

What I claim as new, and desire to secure by Letters Patent, is-

Having the chambers A B made separate and independent of each other and of the tube-sheets O, as and for the purpose herein shown and described.
